Spring behavior

[Isaac OLEG]

Hello,

Repetition I found a little less fast (but efficient) with these
whippen. The weight of the Teflon screw is felt in the lever when
playing.
The springs seem to be not as responsive.

I've see one that was a little noisy too (a very little).

That is more a matter of feel. Bechstein, I believe have used these
whippen before coming back to butterfly.

But sure they are very stable.

Regards.
